You will not be able to compile this file correctly without gcc, because |
|
it is necessary to pack the "wavefront_alias" structure to a size |
|
of 22 bytes, corresponding to 16-bit alignment (as would have been |
|
the case on the original platform, MS-DOS). If this is not done, |
|
then WavePatch-format files cannot be read/written correctly. |
|
The method used to do this here ("__attribute__((packed)") is |
|
completely compiler dependent. |
|
|
|
All other wavefront_* types end up aligned to 32 bit values and |
|
still have the same (correct) size. |
|

/* However, note that as of G++ 2.7.3.2, g++ was unable to |

correctly parse *type* __attribute__ tags. It will do the |
|
right thing if we use the "packed" attribute on each struct |
|
member, which has the same semantics anyway. |

|
Because most/all of the sample data we pass in via pointers has |
|
never been copied (just mmap-ed into user space straight from the |
|
disk), it would be nice to allow handling of multi-channel sample |
|
data without forcing user-level extraction of the relevant bytes. |
|
|
|
So, we need a way of specifying which channel to use (the WaveFront |
|
only handles mono samples in a given slot), and the only way to do |
|
this without using some struct other than wavefront_sample as the |
|
interface is the awful hack of using the unused bits in a |
|
wavefront_sample: |
|
|
|
Val Meaning |
|
--- ------- |
|
0 no channel selection (use channel 1, sample is MONO) |
|
1 use first channel, and skip one |
|
2 use second channel, and skip one |
|
3 use third channel, and skip two |
|
4 use fourth channel, skip three |
|
5 use fifth channel, skip four |
|
6 use six channel, skip five |
|
|
|
|
|
This can handle up to 4 channels, and anyone downloading >4 channels |
|
of sample data just to select one of them needs to find some tools |
|
like sox ... |
